The steps below describe the construction of a line AG which is parallel to segment PQ and passes through a point A outside of PQ: Point G is obtained by using the same compass width and drawing an arc from point E, intersecting the arc drawn from A.
Point G is obtained by using the same compass width and drawing an arc from point B, intersecting the arc drawn from A.
Point G is obtained by using the same compass width and drawing an arc from point D, intersecting the arc drawn from A.
Point G is obtained by using the same compass width and drawing an arc from point F, intersecting the arc drawn from A.
